Nice, I've had the same thought with Fedora Silverblue, but Qube's qvm-
etc tools make everything so much easier.

Indeed R4.1 is using Xen 4.13.1
<https://github.com/xen-project/xen/commits/RELEASE-4.13.1> last commit
was back on May 7th 2020, I can't seem to see any AMD/Ryzen specific
commits that are newer than this date, I was looking at cherry picking
Xen commits related to AMD/Ryzen however I can't find any.
Any and all AMD Related commits I can find were made in 2019 and are
included in the current Xen 4.13.1
So perhaps this is actually a dom0/Linux Kernel issue? Surely if it were
Xen they'd have something committed by now?

I've experimented a bit with Ubuntu and some different kernels. I was
not able to get 5.7.0 kernel graphics to work at all (not even

confirms the amdgpu driver is being used to drive the display. The
default 5.4.0 kernel won't recognize the gpu but graphics do work
without acceleration.
I don't know why graphics are broken in 5.7 (dmesg didn't show any
vga/amdgpu errors) when that is the first kernel to receive AMD Renoir
support. It could be that 5.8 has a fixed amdgpu driver, or that the
presence of power management drivers is required to properly drive the
Vega gpu.
